- the specified liquid product was crushed into small components with the formation of small bubbles of the vapor-gas mixture, while in the tapering channel 10 of the Laval nozzle or nozzle similar to the Laval nozzle, the vapor-gas mixture began to compress, which led to an increase in pressure in vesicles up to 0.5-1, 2 Pa.
- the liquid product filling the mixing chamber 2 was heated due to the intensive heat release in the zones of local hydrodynamic cavitation, the temperature of which increased to 800–900 ° ⁇ .
